. f. This intention thes reference to self pm- 1 pelled road Vehicles and consistsin a method of mounting theenginein the chassis and has I 1 for its object tosecure the required amount 1 ofrigidity betweenwthe engine and the chassis frame and at thesa'metime to secure in manner better than has hithertobeen done a, resilengine and the frame. T j v It has been proposed to interpose between a theinetallic members of theengine and chassis constituting the connection pads'of india rubber or the like, but inarrangements hereient or anti-vibratoryconnection between the 5+5 in Figure 3' partly in section of one of theforward supports and Figure 6is a scrap c t'oforeinuse the rubber pads have permitted toomuchresiliencyji and in other respects sueh arrangements arenot entirely satisfac-' tory .r, w

v Theobject of this inyention is to secure the desired degreeof rigidity of the frame, utilizing the engine for su'ch'purpose, and at the V same time securethedesired limited amount I [of resiliency between the; engine and the 7 frame in a manner better than 'has' been here- ,tofore attained.
